A flywheel is a common machine component, capable of storing rotational energy for later use. When the machine reaches a point where the supply power is inefficient for operations, the flywheel will release its stored energy. Within a standard internal combustion engine, for example, the fluctuating torque produced by the crankshaft during a complete cycle will cause the shaft to have a change in its angular velocity. Through the implementation of a flywheel, inertia mass is provided at the end of the shaft so that the torque will become more balanced. Read more >>

When an aircraft is transporting individuals over long distances, it is important that passengers have access to facilities such as lavatories and aircraft galleys for the means of providing a comfortable experience for all. In order for passengers and crew members to take advantage of the restrooms, coffee and tea makers, sinks, and other facilities and equipment of an aircraft, water must be managed and supplied to each. In this blog, we will discuss the water and waste system of aircraft, allowing you to better understand how potable water is supplied to facilities and how wastewater is removed and stored during a flight operation.

Honeycomb cores first appeared on aircraft in the 1940s when they were used to reduce weight and increase payload & flight distance. They were integrated into aircraft designs as a replacement for the much heavier conventional sheet and stringer or beam support approach. Since their introduction, honeycomb cores have become a basic structural concept throughout the aerospace industry. In the 21st century, nearly every commercial and military aircraft depends on honeycomb cores for their integrity and reliability. There are many substrate materials used in honeycombs, and honeycomb cores can have densities as low as 16 kg/m3 (kilograms per cubic meter). Read more >>

Controlling the pressure rating is often important in ensuring a system can function properly. The required pressure rating of different systems will vary based on the system type and the industry or application it is used in. For example, the pressure requirements of an aircraft will differ greatly from those of an automobile engine. To maintain pressure, many systems use a pressure gauge, which can be set to and maintain a desired pressure. In this blog, we will discuss the six most common types of pressure gauges. Read more >>

Keeping a jet engine running as efficiently as possible is critical. An efficient engine is safer, works better, and uses less fuel to run. As such, operators are always looking for ways to maximize the efficiency of their jet engine. One such way is compressor cleaning. Read more >>
